Abstract

Background: Medical school faculty members have been reported to be highly likely to suffer burnout. Research is being conducted on professional self-concepts as a factor that relieves burnout in many professions. However, there is a paucity of data on the relationship between professional self-concept and burnout among medical school faculty. Professional self-concept means a perception of oneself as a member of the profession. It influences an individual’s thoughts, actions, and emotions. The more positive the professional self-concept, the higher is the self-esteem in the profession, which can contribute to reducing burnout. This study aimed to investigate the professional self-concept and incidence of burnout among medical school clinical faculty members, and to ascertain the factors that affect professional self-concept with respect to burnout.

Methods: A total of 68 clinical faculty members at the Ajou University School of Medicine completed a modified form of the professional self-concept scale and the Maslach Burnout Inventory. We undertook the following statistical analyses: a descriptive analysis to understand the distribution of participants, correlation analysis to indicate associations between variables and a multiple regression analysis to examine the influence of gender, position, and specialty on professional self-concept and burnout, and the effect of each subscale of professional self-concept on burnout.

Results: As professional self-concept increases, burnout decreases. There was no significant difference between professional self-concept and burnout with respect to gender or field of medical specialty, while a significant difference was observed across faculty position levels. Additionally, the professional self-concept subscale, which included satisfaction and communication skill, was found to significantly affect burnout.

Conclusions: This study shows that professional self-concept affects burnout. Through these results, we can infer that professional self-concept functioned to protect medical school faculty from burnout. This may be a strategy that fortifies the professional identity of medical school faculty, and it is suggested that educational programs that are directed toward this goal be established.

Background

Burnout in the workplace is characterized by emotional stress associated with work or with interpersonal rela- tionships factors such as sustained response, leading to emotional exhaustion, depersonalization, and reduced personal accomplishment [1]. It has been shown that burnout is experienced more frequently by professionals employed in providing services to treat psychological, social, and physical problems [2]. Medical school faculty members have been reported to be highly likely to suffer burnout as a result of their job activities, including stu- dent education, research, clinical practice, and other medical administrative duties [3–6]. In particular, med- ical faculty who are also performing clinical duties are under pressure to increase their clinical productivity and, in many cases, are urged to treat patients rather than teach students [7, 8]. Therefore, there are numer- ous medical faculty members interested in student edu- cation who are unable to devote sufficient energy to teaching due to the lack of time and energy [9]. As a re- sult, medical faculty who suffer from burnout also lose morale and experience both mental and physical prob- lems [10].

The effects of burnout among medical faculty are not confined to the individual physician, but may result in the impairment of patient care [11], an increased inci- dence of medical errors and adverse events [12,13], and decreased empathy towards patients [14]. Medical fac- ulty burnout also has a detrimental effect on the educa- tion of medical students, as efforts to improve the quality of education need to be implemented; including enhanced interest in improving curricula and teaching methods. However, the ensuing physical and mental ex- haustion that leads to the burnout of medical faculty may lead to passivity in accepting new and innovative changes [15, 16]. Therefore, rather than looking for a long-term solution to medical faulty burnout, we suggest that efforts to minimize burnout should be considered so that medical practice and medical education may be performed with a high level of quality.

The majority of medical school faculty are overburdened with their respective duties, but not all faculty experience burnout. There may be individual differences even within the same workplace environment in terms of how individ- uals view, interpret, and handle burnout. There has been increasing attention on the idea of professional self- concept, which reduces an individual’s burnout.

Professional self-concept is the perception of what it means to be and act as member of a profession [17].

More precisely, professional self-concept refers to the perceptions of a member of a specific group with his/her skill, knowledge, beliefs, values, and motivation, which are formed and changed in the process of evaluating his/

her own traits and abilities through various experiences

and interactions with others [18–21]. In other words, professional self-concepts are formed through self- reflection and social interaction. Professional self- concept affects an individual’s thoughts, behaviors, and emotions [22,23]. Research in other areas suggests that individuals who have a strong, well-formed professional self-concept have low levels of burnout and are less will- ing to quit their jobs [18, 19]. On the other hand, those who do not have a well-formed professional self-concept tend to fail to function properly in their specialties and experience a high level of exhaustion or resignation without success [24].

Studies in many professions have shown that burnout influences professional self-concept in many professional workplaces. In a study of registered nurses in a univer- sity hospital setting, it was observed that nurses who participated in a professional identity development train- ing program experienced an enhanced professional self- concept and lower levels of burnout [25]. Further, among professional school counselors, a negative correl- ation was found between professional self-concept and burnout [26].

In light of these results, it is our hypothesis that pro- fessional self-concept may be a moderating factor on burnout in medical school faculty members. However, there is a paucity of data on the relationship between professional self-concept and burnout in this highly spe- cialized occupational group, and therefore, it is the aim of this study to delineate the role of professional self- concept in burnout in this group.

Our research questions are as follows:

First, what is the extent/level of professional self- concept and burnout among medical school faculty members?

Second, what are the effects of gender, job position, and medical specialty on professional self-concept and burnout in medical school faculty members?

Third, what is the relationship between professional self-concept and burnout in medical school faculty members?

Methods Participants

The participants of this study were employed clinical faculty members of Ajou University School of Medicine, Gyonggi Province, Republic of Korea. The questionnaire survey, conducted in April 2018, was sent as e-mails to 230 clinical faculty members who were engaged in teaching medical students in the 2017 academic year.

Consent was obtained from all participants, and the questionnaire did not include the name of the partici- pant. A total of 68 questionnaire replies was analyzed in this study.

Measures

Professional self-concept

To measure professional self-concept, the scale for the professional self-concept of nurses developed by Arthur [27] was used in this study, as it is a scale that can evalu- ate various skills and attitudes. Although developed for the nursing profession, there are no items that would be inappropriate to apply to physicians. Only items where the term“nurse” or “nursing” is used were modified for physicians for use in this study. This professional self- concept scale consists of three subscales: professional practice, job satisfaction, and interpersonal communica- tion. Professional practice included leadership, flexibility in adapting to one’s situation, and skills to ensure a com- petent work performance. Job satisfaction was defined as the degree of satisfaction and joy experienced in per- forming one’s job duties. Interpersonal communication refers to empathy and open-mindedness in interpersonal relationships. This instrument consists of 27 items: pro- fessional practice (16 items), satisfaction (7 items), and communication (4 items). As examples, professional practice is assessed through statements such as “Deci- sion-making is one of my attributes,” “When I’m at work and the situation calls, I am able to think of alternatives,

” and “I pride myself on my skills as a doctor.” Satisfac- tion is assessed through statements such as“Medicine is a rewarding profession.” Communication is assessed through statements such as “I don’t believe I am par- ticularly empathic.” Each item was scored on a four- point Likert scale from “strongly do not agree” (one point) to “strongly agree” (four points), and a higher score was deemed to indicate higher levels of profes- sional self-concept. To verify the reliability of this scale, we checked the Cronbach’s α coefficient, which was 0.925 in this study.

Burnout

To assess the degree of burnout among medical school faculty members, we employed the Maslach Burnout In- ventory—Educators Survey (MBI-ES) that was developed by Maslach et al. [1]. This MBI is recognized as the lead- ing measure of burnout and has been validated by exten- sive research conducted over a long period of time. This scale comprises 22 items that survey emotional exhaus- tion (EE, 9 items), depersonalization (DP, 5 items), and reduced personal accomplishment (RPA, 8 items). Each item in this study was measured on a seven-point rating scale ranging from “never” (zero points) to “always” (six points), and higher scores indicated more frequent burn- out occurrences. Cronbach’s α for the scale was 0.905.

Analysis

To understand the distribution of participants by gender, job position, and job specialty, and to ascertain the

characteristics of the questionnaire participants, descrip- tive statistical methods were applied. To identify the relationships between the subscales of variables, correl- ation analysis was conducted. Multiple regression ana- lysis was carried out to analyze the effects of gender, faculty position, and field of specialty on professional self-concept and burnout. Multiple regression analysis was also applied to analyze the effects of the variables assessed by the professional self-concept subscales on burnout.

Results Demographics

The distribution of gender, faculty position, and field of specialty of the study participants is shown in Table 1.

Out of the 230 participants, 68 of them responded (29.6%), and the gender ratio was found to be 1.5 (M:F ratio). The distribution of faculty positions was fairly even, while the most common field of specialty was in- ternal medicine, followed by surgery, and support care medicine.

The analyses of participants’ professional self-concept and burnout are shown in Table2.

Among the professional self-concept subscales, partici- pants scored the highest on professional practice (M = 3.30, SD = 0.41), followed by satisfaction (M = 3.06, SD = 0.56), and communication (M = 2.89, SD = 0.51); while on the subscales of professional practice, participants scored the highest for skill (M = 3.44, SD = 0.38) followed by flexibility (M = 3.37, SD = 0.42), and leadership (M = 3.10,SD = 0.54).

Participants’ scores on the subscales for burnout were ranked as follows: emotional exhaustion (M = 3.02, SD = 0.99), reduced personal accomplishment (M = 2.16, SD = 0.94), and depersonalization (M = 2.01, SD = 1.14), in de- creasing order.

The correlations between variables are shown in Table 3. It can be seen that there exists a statistically significant negative correlation (r = − 0.76, p < 0.01) between profes- sional self-concept and burnout, indicating that higher professional self-concept values lead to lower burnout values. All the subscales of professional self-concept showed significant negative correlations with burnout, with their absolute values decreasing from 0.69 for satis- faction (p < 0.01) to 0.60 for communication (p < 0.01) and professional practice (p < 0.01).

We investigated the effects of gender, faculty position, and field of specialty on professional self-concept and burnout as reported in Table 4. Gender and field of spe- cialty were not found to be associated with professional self-concept and burnout, while faculty position did signifi- cantly affect them. Faculty position had a positive effect on professional self-concept, but a negative effect on burnout.

The analysis of the effect of professional self-concept on burnout is shown in Table5. Professional self-concept ex- plained 60% of the variance (F = 30.13, p < 0.001) for

burnout. It was also observed that while professional prac- tice did not have a significant effect on burnout, satisfac- tion (β = − 0.41, p < 0.001) and communication (β = − 0.30, p < 0.01) had significant negative effects.

Discussion

This study investigated the effect of professional self- concept on burnout in medical school clinical faculty members. The study results are as follows.

First, the analysis of the relationship between profes- sional self-concept and burnout found negative correla- tions between professional self-concept and all burnout subscales, emotional exhaustion, depersonalization, and reduced personal accomplishment. That is, medical fac- ulty with higher levels of professional self-concept experi- ence less burnout. Our results can be understood within the framework of Edwards and Dirette [28], whose study demonstrated a significant negative correlation between occupational therapists’ professional self-concept and burnout. Our results confirm that strengthening the level of professional self-concept could lead to decreases in burnout occurrences. In particular, the results show that professional self-concept is strongly and positively related to the personal accomplishment sub-scale of the MBI.

Hence professional self-concept appears to be strongly in- fluenced by experiencing a sense of competence and ac- complishment in one’s field of expertise.

Second, it was found that the higher the faculty pos- ition, the higher the level of professional self-concept with accompanying lower levels of burnout. This implies that junior faculty members experience lower levels of professional self-concept than senior faculty members, and have concomitantly higher levels of burnout. Earlier investigations of medical school faculty burnout [29–31], concluded that in their early career years, faculty were more susceptible to high levels of emotional exhaustion, which agrees with our results.

have less burnout than junior faculty may be understood in terms of accumulated career experience, which is ac- companied by enhanced job skills and control abilities so that high standards of competence are achieved, lead- ing to relatively decreased job-related stress or burnout [29,32]. In addition, junior faculty members work longer hours than senior faculty members, receive more emer- gency calls, and are subject to irregular work-life prob- lems [33, 34]. Family environment may also be a contributing factor for burnout. Junior faculty are youn- ger and frequently have families with young children to support [30], which may be contributing factors to con- flict and burnout in the workplace and at home.

Third, while the subscales of professional self-concepts, such as leadership, flexibility, and skill did not have a sig- nificant effect on burnout, our study found that job satis- faction and communication factors had a significant negative effect. Medical school faculty form various inter- personal networks with patients, medical students, nurses, and administrative staffs in two workplace environ- ments—at hospital and at school. The difficulty in inter- personal communication is a factor that elevates the degree of burnout. It was shown in an earlier analytic study of the relationship between burnout and job satis- faction in surgeons that lower job satisfaction was corre- lated with a significantly greater incidence of burnout [9].

Another study addressed the relationship between regis- tered nurses’ training in communication skills and burn- out, and determined that communication skill training played an active role in ameliorating burnout among nurses [35]. We were therefore able to ascertain from the aforementioned studies whether the extent of medical school faculty satisfaction with their duties and how well they are able to communicate with whom they interact in their workplace significantly affect their levels of burnout.

The significance and implications of this study are as follows.

First, the main point of the current study is that we were able to explore the relationship between profes- sional self-concept, and confirm the function of profes- sional self-concept in ameliorating this burnout. The findings of the study do not necessarily demonstrate a causal relationship between professional self-concept and burnout. Nonetheless, it may be considered that

professional self-concept is a possible factor serving a protective function for the medical faculty member’s mental well-being. In particular, it is our opinion that one of the major findings of this explorative inquiry is the confirmation of the significant role of job satisfaction and interpersonal communication skills in reducing the degree of burnout among medical faculty.

Second, we would point out that junior medical faculty have low levels of professional self-concept and high burn- out rates. To enhance their professional self-concept levels and decrease burnout rates, junior medical faculty need faculty development and mentoring programs. We suggest that these results be brought to the attention of medical school deans and administrations so that necessary insti- tutional support can be provided.

Nevertheless, we must note the limitations of the current study to suggest directions for future follow-up studies. We find the distribution of gender, position, and specialty to be relatively balanced, even with a small number of partici- pants. In particular, we think the 6:4 gender ratio in this study is not terribly important. Nevertheless, this study has limitations in that it was conducted in one medical school with a small sample. It is necessary to conduct follow-up studies in more number of medical schools with larger samples. Moreover, this study applied a standardized ques- tionnaire that assessed self-reported measures; other stan- dardized instruments could also be used advantageously.

Professional self-concept is one aspect of the educational process that gradually develops through adaptation to job duties, and therefore requires continuous evaluation at each step over a long period. There is also a limitation in the overall measurement of burnout, and the use of quantita- tive instruments to measure the psychodynamic aspects of this psychological phenomena. To better understand the burnout phenomenon, in-depth interviews along with qualitative research is deemed imperative.

Conclusions

This study ascertained that professional self-concept functions to protect medical school faculty from burn- out. This may be a strategy that fortifies the professional identity of medical school faculty, and it is suggested that educational programs directed toward this goal be established.
